Chemical Structure

4-Methyl-1H-pyrazole-3-carbohydrazide CAS 94447-15-1 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

4-Methyl-1H-pyrazole-3-carbohydrazide (CAS 94447-15-1) is a high-purity analytical reference standard with the molecular formula C5H8N4O and a molecular weight of 140.14 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, 4-Methyl-1H-pyrazole-3-carbohydrazide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 4-Methyl-1H-pyrazole-3-carbohydrazide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
